Please post your code and explain, which problems you have. It is easier to suggest a solution than to guess a problem.

I don't have a code. With webread I get an html that is very confused. What I need is a table in which in first column I have the names of the categories and in the second column the YTD Return%. For example:
RV China - A Shares 0.65
RV India 18.94
RV Dinamarca 14.09
and so on. How Can I do it? Thanks!

URLREAD expects US-style usage of commas and stops in numbers. So in a number like 150,228.17 it will ignore the comma and return 150228.17. We should re-write URLFILTER so that it can read numbers that use commas as the decimal point, but in the meantime there is a workaround.
For financial numbers, if you are certain there will be exactly 2 digits reported after the decimal point (which appears to be the case on www.morningstar.es/), then just take the output of URLFILTER and divide by 100.
url = 'http://www.morningstar.es/es/tools/categoryoverview.aspx?filterId=-1&lang=es-ES';
name = 'RV India';
raw_price = urlfilter(url,name)
actual_price = raw_price/100
raw_price =
1974
actual_price =
19.7400
